AU in which Zog was the one to manipulate himself the entire time into doing everything he has done + rescuing Talion and becoming his ally only to make both of them spiral and later Talion becomes a nazgul and this is up to debate if it was a consequence of their actions or it was up to Talion exclusively. The fact is that it's the event that pushes Zog into this huge manipulation game because he can't accept Talion's fall and so he has to destroy himself in the process to; he also can't get over the fact that he was defeated by Talion so he's also taking revenge. It ends with both of them dying.
